Duncan Stutterheim, the mind behind ID&T, one of the world’s biggest festival brands, is calling it quits after 23 years, citing age and a lack of passion for the dance music scene.

In an interview with Volkskrant, the 43-year-old Stutterhelm, who was responsible for world-renowned festivals such as Mysteryland, Sensation, and the “Tomorrow” family, acknowledged that he was too old for the electronic music scene. “We just felt we grew out,” he told the Dutch newspaper. “It has to do with the changing music… For example Martin Garrix’ music, I can appreciate it, but I’m not dancing to it. It also has something to do with my age.”

The decision comes after ID&T’s purchase by SFX Entertainment in October 2013. “SFX deserves the energy I had seven years ago.”

Stutterheim’s last day will coincide with the 15th anniversary of Sensation on July 4.
